Overdrive/PublishDrive for additional ebook distribution
I've tested Overdrive/Publishdrive with one book to learn how it works and produce an epub acceptable to them. It only took three days to figure out it's better to use Calibre and edit Metadata using Sigil. You cannot use the one from Lulu.
This is where libraries order their books (Overdrive through PublishDrive). They accept individual authors.
You can select/deselect territories and retail outlets and they have a long list of new ones.
If you get stuck, feel free to ask. It was torture knowing nothing. I'm more than happy to help.
